In environmentalinformatics-marburg/Reot: Empirical Orthogonal Teleconnections in R

Description

The function cuts a specified number of layers off a RrasterStack in order to create lagged RasterStacks.

Usage

cutStack(data, tail = TRUE, lag = NULL)

Arguments

data	a RasterStack
tail	logical. If TRUE the layers will be taken away from the end of the stack. If FALSE layers will be taken away from the beginning.
lag	the number of layers to take away.

Value

a RasterStack shortened by lag either from the beginning or the end, depending on the specification of tail
